You’re about $8 away from one of the coolest beauty tools I’ve seen in a while. Everyone should have a glass nail file.
Slightly textured glass completely smoothes jagged edges from nails without any rough corners left behind. Just a quick rinse under water or alcohol to clean or sanitize, and it’s good as new. The glass maintains the integrity of your nails unlike emery boards that can shred natural nails and make them rough and peel.
You’ll see a big difference right away in the strength and texture of you nails- you won’t use your old file again.
